Page 8: Safety Notice
www.baldormotion.com Product notice Only qualified personnel should attempt the start-up procedure or troubleshoot this equipment. This equipment may be connected to other machines that have rotating parts or parts that are controlled by this equipment. Improper use can cause serious or fatal injury. Safety Notice Intended use: These drives are intended for use in stationary ground based applications in industrial power installations according to the standards EN60204 and VDE0160.
Page 9 WARNING: A regeneration resistor may generate enough heat to ignite combustible materials. To avoid fire hazard, keep all combustible materials and flammable vapors away from the brake resistors. Baldor regeneration resistors are neither internally fused nor thermally protected and under extreme conditions, can cause a fire hazard if not suitably protected or rated for the application.
Page 10 CAUTION: Violent jamming (stopping) of the motor during operation may damage the motor and drive. CAUTION: Operating the MicroFlex in Torque mode with no load attached to the motor can cause the motor to accelerate rapidly to excessive speed. CAUTION: If the drive enable signal is already present when power is applied to the MicroFlex, the motor could begin to move immediately.

I/O information. A separate fused 24V supply should be provided for the MicroFlex. If other devices are likely to be powered from the same 24V supply, a filter (Baldor catalog number FI0014A00) should be installed to isolate the MicroFlex from the rest of the system.
Page 33 Baldor representative. The motor must be capable of being powered by an inverter PWM output - see section 8.1.3 for details. The motor can be connected directly to the MicroFlex or through a motor contactor (M-Contactor). The motor outputs are conditionally short-circuit proof.
Page 34: Motor Circuit Contactors
If required by local codes or for safety reasons, an M-Contactor (motor circuit contactor) may be installed to provide a physical disconnection of the motor windings from the MicroFlex (see section 3.5). Opening the M-Contactor ensures that the MicroFlex cannot drive the motor, which may be necessary during equipment maintenance or similar operations.

Page 41: Feedback
www.baldormotion.com Feedback 4.1 Introduction Three feedback options are available for use with linear and rotary motors; incremental encoder, encoder with SSI (Synchronous Serial Interface), or resolver. There are some important considerations when wiring the feedback device: The feedback device wiring must be separated from power wiring. Where feedback device wiring runs parallel to power cables, they must be separated by at least 76mm (3 in) Feedback device wiring must cross power wires at right angles only.
Page 42: Encoder Feedback - X8
D-type connector. Connector X8 includes a ‘Sense’ pin, which is used to detect the voltage drop on long cable runs. This allows the MicroFlex to increase the encoder supply voltage on pin 12 to maintain a 5V supply at the encoder.

However, if Hall connections are not present, it will be necessary for the MicroFlex to perform an automatic phase search sequence each time it is powered. This will cause motor movement of up to 1 turn on rotary motors, or one pole-pitch on linear motors.

Configuration 6.1 Introduction Before powering the MicroFlex you will need to connect it to the PC using a serial cable and install the supplied PC software Mint WorkBench. This software includes a number of tools to allow you to configure and tune the MicroFlex. If you do not have experience of software installation or Windows applications you may need further assistance for this stage of the installation.

Page 83: Troubleshooting
If you have followed all the instructions in this manual in sequence, you should have few problems installing the MicroFlex. If you do have a problem, read this section first and check the help file in Mint WorkBench. If you cannot solve the problem or the problem persists, the SupportMe feature can be used.
Page 84: Status Led
If multiple errors occur at the same time, the lowest numbered error code will be flashed. For example, a MicroFlex which has tripped on both feedback error (code 5) and over-current error (code 3) will flash error code 3. If the drive is already displaying an error code when a new error with a lower code occurs, the drive will start flashing the new code.

Accessories A.1 Introduction This section describes accessories and options that you may need to use with your MicroFlex. Shielded (screened) cables provide EMI / RFI shielding and are required for compliance with CE regulations. All connectors and other components must be compatible with the shielded cable.
Page 96: A.1.1 Fan Tray
The fan tray (Baldor part FAN001-024) provides sufficient cooling for the 3A, 6A or 9A MicroFlex. It requires 23 - 27.5VDC at 325mA, which may be sourced from the same filtered control circuit supply used for the MicroFlex. The MicroFlex is UL listed (file NMMS.E128059) when used in conjunction with the fan tray, mounted exactly as shown in Figure 45.
Page 97: A.1.2 Footprint Filter
The single-phase footprint AC power filter (Baldor part FI0029A00) provides mounting holes for the MicroFlex and fan tray. This allows the filter, fan tray and MicroFlex to use the minimum panel mounting space. See section A.1.3 for details of filter FI0029A00.
Page 98: A.1.3 Emc Filters
A.1.3 EMC filters AC filters remove high frequency noise from the AC power supply, protecting the MicroFlex. These filters also prevent high frequency signals from being transmitted back onto the power lines and help meet EMC requirements. To select the correct filter, see sections 3.4.7 and 3.4.8.

Page 107: B Control System
Control System B.1 Introduction The MicroFlex can be configured for three basic control modes: Current (Torque) control. Velocity (Speed) control. Step and Direction following/gearing. The mode you require is selected in Mint WorkBench using the Commissioning Wizard. You can subsequently change between these control modes using the Tools, Control Mode menu item or by using the CONTROLMODE keyword in the Command window (see the Mint help file).
Page 108: Current (Torque) Control
B.1.1 Current (Torque) control Setting the control mode to Current Control configures the MicroFlex or MicroFlex as a torque amplifier, as shown in Figure 51. Here, a torque reference is obtained from a specified source: Mint WorkBench A host using the ActiveX control Analog input The source provides a signal that is fed into the Torque profiler.
Page 109: Velocity (Speed) Control
B.1.2 Velocity (Speed) control Setting the control mode to Velocity Control configures the MicroFlex as a speed amplifier, as shown in Figure 52. Here, a speed reference is obtained from a specified source: Mint WorkBench A host using the ActiveX control Analog input The source provides a signal that is fed into the Speed controller.
Page 110: Position (Step And Direction) Control
B.1.3 Position (Step and Direction) control Setting the control mode to Position Control (Step and Direction) configures the MicroFlex as a positioning system, as shown in Figure 53, capable of following a position command signal. The up down counter and gearing interpret the step and direction signals and use them to generate a position demand signal.

C.1.2 MicroFlex compliance When installed as directed in this manual, MicroFlex units meet the emission limits for an ‘industrial’ environment, as defined by the EMC directives (EN61000-6-4: 2001). To meet the more stringent emission limits of the ‘residential, commercial and light industrial’ environment (EN61000-6-3: 2001), the MicroFlex must be mounted in a suitable metal cabinet incorporating 360°...

With this technique, a good earth/ground shield can be achieved. EMC filters The filter should be mounted next to the MicroFlex. The connections between the MicroFlex and the filter should use shielded (screened) cables. The cable shields should be connected to shield clamps at both ends.
